Watch Killebrew, Mantle battle in classic 'Home Run Derby'

When old school baseball fans think of home run derbies, they don't think of two-hour made-for-TV reality shows with the likes of Brian Dozier, Todd Frazier and Josh Donaldson.

One-on-one showdowns between hall of famers like Harmon Killebrew and Mickey Mantle? Now THAT is a home run derby!

You won't see those legends at tonight's festivities at Target Field, but you can watch them face off HERE thanks to the miracle of YouTube.

Killebrew and Mantle were two of the 19 major leaguers who competed in the "Home Run Derby" TV series that originally ran in 1960 and has aired occasionally on ESPN networks in the years since. Each episode featured two sluggers battling it out in Los Angeles' Wrigley Field, with sportscaster Mark Scott providing the call.

Mantle won in the series' first three episodes before taking on Killebrew, who was still a year away from moving to Minnesota with the rest of his Washington Senators. Their matchup came down to the final swing (Spoiler alert: You'll have to watch the video to see who won).

Killebrew went on to make three more appearances on the series. He posted a 6-5 victory over Cleveland's Rocky Colavito, and he lost nail-biters to St. Louis' Ken Boyer and San Francisco's Willie Mays.

This "Home Run Derby" series lasted only one season, due, in part, to the death of Scott just days after the final episode aired.
